 **Description:** Did you ever wonder if you can build a personal tracking platform similar to how Google tracks you but without Google tracking you? Come and join me for an informal session where I will show you how easy it is to build a platform like this using FOSS GIS. Note the presentation will use QGIS but also focus a lot on other related tools needed in the workflow.
